Ch. 19 Long term Control of BP

Question 1

Long term control of BO is related to? And is based on?

Answer 1

maintaining homeostasis of body fluid volume.

Maintaining a balance b/t intake/output of fluid

Question 2

What is the bodies response to: Increase in extracellular fluid results in increased blood volume and arterial pressure

Answer 2

kidneys excrete excess extracellular fluid and returns the pressure to normal

Question 3

Determinants of Net Fluid Movement Across the Kidney Capillaries

Answer 3

• > capillary BP
• > Colloid ossmotic pressure
• > Capsular pressure

Question 4

Decreased Plasma Protien: ___
Hemorrhage: _____

Answer 4

Increased GFR
inmcreased GFR 
 -> Causes Edema
